Could I be pregnant, what are my chances?

Okay, so yesterday I was at my boyfriend's we have had sex before but I have never used any method of birth control. My parents don't know. I was on my period June 14 through the 21st. During the tine if my period my boyfriend held all of his cum. Then yesterday we had sex. We did it, he didnt cum. Then, i gave him a hand job and he came on my hand. We did it again a few hours later, he didnt cum. Then, again, a hour later I gave him a hand jib and he came in my hand. But, even though he didn't come in me could I be pregnant? Idk if I was ovulating.
